Using these sheets is a breeze. Just put the fitted sheet on your queen - sized 60cm deep bed, using the tags to make sure it's in the right position. Then place the pillowcases on your pillows. When it comes to washing, you can use your regular washing machine on a gentle cycle with mild detergent. Avoid using bleach as it can damage the cotton. After washing, tumble dry on low heat or hang them to dry. This will help maintain the softness and durability of the sheets. And if you want to keep them looking their best, iron on a low - medium setting when needed.
